Colt 16" Enhanced Patrol Rifle Upper Receiver Assembly, stripped

law enforcement EPR upper receiver group with Centurion M-LOK rail

This is the stripped upper receiver group, taken off a new Colt EPR rifle with M-LOK thin performance rail from Centurion.  The Colt Enhanced Patrol Rifle is an upgrade to the 6920 family of Colt rifles.  The EPR is designed for law enforcement, but available commercially as well. 

The Colt Enhanced Patrol Rifle (EPR) is the next evolution in the world's most dependable, thoroughly field-tested patrol rifle. Featuring an extended handguard that accepts modular rail segments for mounting a wide variety of pro-grade optics, lighting, and ergonomics-enhancing accessories, and a Colt factory low profile gas block.  The EPR upper receiver group features the Centurion ultra-thin high performance rail, and is a hot looking upper and makes for a fun to shoot gun.

This upper is a take-off from a factory new Colt LE6920 EPR manufacture red in late 2020 or early 2021.  This vintage of Colt uppers features the Cerro forged upper receiver without CAGE code, and Centurion rails in white branding.  Later rails were changed to have engraving and not white etched lettering.  The rail is model ML1513, which is now a legacy model.
